Malicious Browser Extensions Becoming More Common

674262_bug_pc_virusAttacks on web users are becoming all too common. Kaspersky Lab’s senior security researcher, Fabio Assolini, says “[The user] needs to know that an extension can access everything you do in the browser, all the data, passwords and the websites visited. So it’s very important not to install unknown extensions. The situation gets worse when the malicious extension is hosted in the official Chrome store, as we noticed in some attacks.” All versions of the Chrome browser list which permissions each and every extension is granted, and Assolini recommends that you check that list regularly. Even installing something as simple and well-known as an ad-blocker or a notepad for the browser can result in infection. He also recommends that Chrome users avoid installing any extension that asks for access to a ton of personal data, regardless of whether the program is trusted by others or not. Google has been taking steps towards protecting its users. In June 2013, Google updated Chrome so that extensions that were not in the Chrome Web store could not be installed on the browser. Any new extensions had to be added through the built-in “extensions” page. While many people complained, Google explained that this was because they could not remove all of the malicious extensions that existed on other websites, but they could control the ones available in their own store. Often, Google finds these extensions and quickly removes them not only from the Store, but from any browser that might have installed them before the company discovered them. In addition, Google also says they’ve started to analyze and test every extension that gets uploaded to the Web Store, and that they don’t even make it to the store if they are found to be malicious. However, this doesn’t mean you’re protected as extensions automatically update. This means that if a good extension is hijacked and infected, the next update will be malicious, even if the original download was not. The important thing that you can do in your web browsing is to verify that your extensions do not have any permissions they shouldn’t, whether you use Firefox or Chrome. In addition, be careful about what you install to ensure that you don’t accidentally introduce dangerous malware to your computer.
